Learn About Lead
Loudoun Water’s distribution system is lead free. The term distribution system is used to collectively describe the facilities, pipe, and other equipment used to supply water from its source up to the privately owned service line. The purpose of distribution system is to deliver water to the consumer with appropriate quality, quantity and pressure. The privately owned service line typically begins at the water meter near the edge of the property being serviced. The homeowner (consumer) is responsible for the service line,
It is important, however, for consumers to understand how lead can enter your drinking water, the risks, and how to prevent exposure.

- Flush faucets before using water for cooking or drinking: Run your cold water tap until you notice a temperature change, then run for an additional two minutes before using it for drinking or cooking. This brings in fresh water from the lead-free water main in the street. (Conservation Tip: save the water for other purposes, such as plant watering)
- Use only water from the cold-water tap for drinking, cooking and especially for making baby formula. Hot water may contain higher levels of lead.
- Use filtered tap water for drinking, cooking, and baby formula: Be sure to select a filter certified to meet NSF Standard 53 (www.nsf.org) for lead removal.
- Clean faucet aerators every three months.
